It is said that buffer is used when any circuit has to drive large outputs. why is buffer used?..

Answer / rinki

in buffer i/p impedance is infinite and o/p impedance is zero.
In a unity gain buffer voltage is transfered unchanged from input to output without any drop.so by using a buffer in a opam circuit we can drive large outputs.
